Abstract
The paper is devoted to the development of the principles of early detection of ice and frost formations on the contact network of electrified railroads. The method considered in the paper is relevant for use on low-intensity crossings equipped with fully compensated contact suspension. The paper substantiates the possibility of determining the fact of the beginning of ice deposition by measuring the force at the point of fixing the fixed roller of the contact network compensator. On the basis of the performed analysis the optimal place of installation of strain gauge measuring body of the system of early detection of ice formation is proposed. A method of analyzing the obtained data to isolate the variable component of the wire weight is proposed. The paper also gives a review of the existing methods of de-icing and their evaluation.
